Answer:

Photoperiodism

Explanation:

The process explained in the question is called "Photoperiodism" which refers to the plants' reaction to the length of the dark and light period in a day.

When the dark period is interrupted with a certain period of artificial lighting, the plant thinks that the day had a longer period where it's "light" than it is "dark" so it gets tricked into flowering. Same concept can be applied in reverse for the plants who flower during longer periods of dark.

I hope this answer helps.

Vanyuwa [196]
The type of learning that the young sea otter used to be able to perform this task is social learning.
This means that the young otter learned what it is supposed to do from its surroundings - and what is surrounding it is its society of other otters. It is social learning because the otter didn't learn on its own that it needs to break open shells in order to eat what is inside, but rather it saw what the other otters were doing and thus learned it.
